STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

Score
serBPutative phosphoserine phosphatase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homolgy; enzyme. (342 aa)    
Predicted Functional Partners:
hisI
Bifunctional: phosphoribosyl-AMP cyclohydrolase (N-terminal); Function of homologous gene experimentally demonstrated in an other organism; enzyme; In the N-terminal section; belongs to the PRA-CH family.
  
  
 0.979
serC
3-phosphoserine/phosphohydroxythreonine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily.
  
 
 0.951
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
  
 0.935
trpB
Tryptophan synthase, beta protein; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
  
 
 0.923
sdaA
L-serine deaminase I; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the iron-sulfur dependent L-serine dehydratase family.
   
 
 0.921
ilvA
Threonine deaminase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA.
    
 0.918
PSHAa1719
Phosphatidylserine synthase; Function of strongly homologous gene; enzyme.
    
 0.905
trpA
Tryptophan synthase, alpha protein; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.
   
 
 0.903
cysE
Serine acetyltransferase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
    
 0.854
hisF
Imidazole glycerol phosphate synthase, subunit with HisH; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit.
